Varieties of Right Ventricular Diastolic Function in Patients with Non-Obstructive Hypertrophic Cardiomyopathy

34 subjects undergoing cardiac catheterization, including 14 normal subjects (evaluated for chest pain with normal hemodynamics and no significant coronary stenosis), 9 patients with asymmetric septal hypertrophy (ASH), and 11 patients with apical hypertrophy (APH). Excluded: obstructive hypertrophic cardiomyopathy, right ventricular free wall hypertrophy, coexistence of ASH and APH, valvular heart disease, coronary artery disease, or congenital heart disease.
